FERROIN SOLUTION AR 0.025 M Redox Indicator
Ferroin solution is a dark red solution of a complex formed between iron(II) ions and 1,10-phenanthroline. It's commonly used as a redox indicator in analytical chemistry, particularly in cerimetry, due to its reversible color change from red to blue upon oxidation
Ferroin is suitable as a redox indicator, as the color change is reversible, very pronounced and rapid, and the ferroin solution is stable up to 60 °C.
Properties:
- Physical State: Liquid.
- Odor: Odorless.
- Solubility: Soluble in water.
- Density: Approximately 1.006 g/cm³.
Composition: A complex of iron(II) ions (Fe²⁺) and 1,10-phenanthroline [Fe(o-phen)3]²
Ferroin serves as an indicator of oxidation reduction reactions in titrimetric analysis. Ferroin is the complex of 1,10-phenanthroline and Fe(II). It is also used as a catalyst for Belousov−Zhabotinsky reaction.
Dosage
A redox indicator (also called an oxidation-reduction indicator) is an indicator which undergoes a definite color change at a specific electrode potential. ... In these systems, the metal changes oxidation state.
Remarks
Ferroin solution is relatively stable, especially when stored properly
